When you try to interpolate the camera with a CameraType that’s not scriptable, you’ll get the following error: “Attempted to use interpolation with a camera mode other than scriptable.”
This is a bit misleading. It’s telling you that the “camera mode” needs to be Scriptable, which can lead to confusion of “How can I set the CameraMode to scriptable? I can only set it to LockFirstPerson and Classic!” The wording should be changed so it says the camera type needs to be set to Scriptable.
